Answer.

Buccinator Mechanism

It refers to the continuous band of muscles which surrounds the dentition and are tightly anchored at pharyngeal tubercle of occipital bone.

“Understanding the role of the buccinator mechanism in oral health”

• Buccinator mechanism begins with decussating fibers of orbicularis muscle which joins the right as well as left fibers of lip. These constitutes anterior component of buccinator mechanism.
• Buccinator mechanism then follows laterally and posteriorly at corner of mouth which joins other fibers of buccinators muscle which are inserted in pterygomandibular raphae.
• At pterygomandibular raphae fibers of buccinators muscle interwind with fiers of superior constrictor muscle and run posteriorly and medially to fi with pharyngeal tubercle.
• All muscles in buccinator mechanism act like a rubber band which tightly surrounds the mandible.

Clinical Significance

• Imbalance in buccinator mechanism causes malocclusion.
• In oral habits such as thumb sucking, tongue thrusting balance between buccinators mechanism and tongue become lost which leads to open bite, increased proclination and constricted maxillary arch.
